Title:
ANTIFOULING COATING MATERIAL COMPOSITION
Document Type and Number:
Japanese Patent JP3173974
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain an antifouling coating material composition, preservable for a long period without increasing the viscosity and causing the gelation when kneading the composition and capable of retaining the antifouling performances for a long period by kneading an antifouling coating material containing a copolymer having carboxyl groups as a vehicle component with an antifouling agent containing a metal.
SOLUTION: This antifouling coating material composition comprises (A) a binder containing a resin, containing carboxyl groups, having 20-400, especially preferably 50-250 acid value (preferably the one having preferably 1000-100000, especially preferably 5000-50000 weight-average molecular weight), (B) an antifouling agent containing a metal (e.g. cuprous oxide, basic copper carbonate or manganese ethylenebisdithiocarbamate) and (C) a monobasic acid compound containing carboxyl group (e.g. acetic acid, propionic acid, butyric acid or valeric acid). The ratio of the carboxyl groups contained in the component (C) to the total carboxyl groups contained in the component (A) is preferably 0.3-3.0, especially preferably 0.5-1.5.
